LLOYD, oF CHICAGO, ILLINOIS, AssIGNOR TO w. @LLOYD COMTANL'OF y f' s CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS LOOSE-:LEAF :BINn'ERi n Applicationv led June 17,

This invention relates particularly to looselea-f binders,A and the primary object 1s to 4provide improved extensionmeans for chain- .posts in binders of the type in which only one ofV the clamping-members is4 equlpped with take-up mechanism. y f ,The invention is illustrated ina preferred embodiment in the accompanying drawing, in Which- VFig. l is a sectional view of a binder embodying theinvention; Fig. 2, a broken sectional view taken as indicated at line 2 of Fig. l; Fig. 3, a similar sectional view illustrating a modilication; Fig. 4, an elevational Vview of a member which, in Fig. 3 is shown insection housed within a hollow clampingmember; and Figr, a partly sectional view of one of the rotary connectors shown in Fig.'1. n c .Y

vReferring to Figs. l, 2 and 3, A and A .designate the clamping-members of a looseleaf binder which may, if desired, be equipped with, `cover-sections;V B, B', flexible posts (chain-posts) connecting the clamping-members; and C, take-up mechanism housed within the clamping-member A', said mechanism comprising nuts 1 `mounted -on a right and -left Y `threaded rod 2, which is journalled ,against endwise movement within the clamping-member A. :j Y I y y f Theclamping-member Af is equipped at its inner side with guides 3 about which the fiexible posts extend, the ends of the flexible posts which are housed within-the clampingmember being connected with the nuts l by means of pins 4. I

The end-links of the flexible posts are designated 5. 'They are provided with reduced threaded extensions 5, Y Y f 1, In accordance with the present invention, the clamping-member A, which has secured therein blocks, is equipped with rotatable connectors,V or screw devices 7. Ordinarily, before extensions are applied, to the flexible posts, the threaded studs 5a ofthe terminal llinks of the chains are connected with the nuts .7. Then the binder has been iilled to a point requiring extension to be made, extension post-sections 8 are introduced. `Thisis accomplished l by disconnecting the terminal 1929.` sei-iai No. 371594.*

sections in the manner illustrated inFig. 1;-

, Each of the screw-elements A7,i1`1thefillustration given, threaded sleeve-portion 7?, an angular shankthrough the block 6 and affords a bearingI in kwhich the member 7 isljournalled and housed.

The bore-9 is provided with an enlarged or counter-sunk portion 9a, the bottom of which -aiiords'a shoulder upon which the iange 7c bears. A thick washer, or spacing ring, 10is interposed between the flange?C and the outer wall 11 of the clamping-member A. =.A` circular opening lla, co-axial with the bore^9, is provided to enable a key tobe inserted, the key receiving the angular shank 7 b and servingV as a means for rotating the member 7N' It-will be understoodthatthe member 17 and thes'pacing-rings 10 maybe entered in the chambers with whichthe` blocks are provided, 'andtheA` blocks may then be inserted clamping-member A.

' The post-sections k8 are-providedfat one i end witha reduced threaded stud 8a and at the other end with `a threaded :socket 8i.

Portions 82? correspondwith'the Vportions' 5aL of the terminal links. 5, and the-threaded sockets 8b correspond `lwiththe threaded socketsoi:l the member 7. 'l

comprises f an Ainternally 455 portion 7 b, and a flange/7c.. A bore ,9 extends'` sfo One or more extension-sections maybe conv nected with each flexible post, as desired.

In the modification shown in Figs. 3 and 4, 6aL designates a housing-.member which may be used as a substitute ,for the blockk 6. This comprises a U-shape member 61? and a barrel,

or tubular member,6c. The'tubular? member 6c. is provided with a reduced lower end-which sunk -bore in which is journalled ascrewzelement 13V which comprisesa: reduced 'threaded l portion 13a, an angular shank-portion 13",

and an interposed flange 18C. A thick washer 14 is interposed between the flange 13C and the opposed wall of the clamping-member A. A double socketed post-section l5 has one end connected with the externally threaded portion 13a ofthe screw element 13. fThe other internally threaded socket may connect with `the threaded stud 5a of the terminal link 5 .of the chain-post. `As shown more clearly in Fig. 3, the bearing ,6C is Yprovided `with areduced lower end which extends through the lower wall of the U-shaped memberrh.

Binders are now upon the market in'which the terminal links 5 are provided wit-h .threaded studs; hence, it is preferred to employ the form Iof. connecting-member designated 7.

Use of the substitute connectingmiember 13 requires either the use of a special extensionsectionof the form shown in Fig. 3, that is, one havingthe'sockets at both ends; or, if the arrangement shown in Fig. l is to be reversed, the terminalllink of vthe chain-post .should beprovided with an internallythre'aded socket instead-of the externally threaded only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed `as broadlyy as permissible, in view ofthe prior art.

5W hat I regard as new, and desire tosecure Y by Letters Patent, is:
